The RF Equalizer receives the RF AGC AMP's output signal and corrects the gain and frequency characteristics
according to disc type and speed. Our RF is used in common with the RF EQ that has similar frequency
characteristics. The RF EQ has 3 independent EQ characteristics, namely that of DVD 1X, CD 1X, and CD 2X.
The RF Equalizer is composed of the SYMMETRIC ZERO HPF and the 9th degree BESSEL LPF. The
SYMMETRIC ZERO HPF's transmission function is:
H(s) = K(S

), and is combined with BESSEL LPF to make RF EQ characteristics.
The RF EQ has predetermined frequency characteristics according to disc type and speed mode. The minute
adjustments of frequency and BOOST gain are carried out by Add 0CH's EQ_FREQ and Add 0BH's EQ_BOOST
and EQG_CEN. The gain adjustment of the Peaking frequency is carried out by the combination of GAIN (3-9dB,
2dB/STEP) selected by EQG_CEN, and GAIN (-4.0-+4.0dB, 0.5dB/STEP) selected by EQ_BOOST. The
selection of the Peaking frequency is made by the EQ_FREQ.
Of the RF EQ characteristics from SPEED_SEL selection, the characteristics when EQ_FREQ=0%,
EQG_CEN=5dB, and EQ_BOOST=+1dB have been shown below.
